Remember those bulletproof windbreakers from Snow Crash? They looked good, they wore well, and they could stop a 9mm round?

I don't know if you'd call this a windbreaker or not, but it's close enough for government work. This jacket weighs only 3kg (about 6.6 pounds) and can stop up to a 7.62mm round from a Tokarev military rifle. On top of that, they say it's also proof against impact trauma, cutting and stabbing, and even hypodermic needles.
